CURRENT-COLLECTOR SUPPORT.

Application filed September 30, 1921. Serial No. 504,430.

To all whom it may concern:

Be it known that I, ELLIS S. LINCOLN, a citizen of Sweden, residing atMansfield, in the county of Richland and State of Ohio,

have invented certain new and useful Improvements in Current-CollectorSupports, of which the following is a specification.

My device relates to trolley poles for use in supporting currentcollecting devices upon cars or busses and while it may be used in theordinary track system of transportation, it is particularly adapted tothe trackless trolley system of transportation.

My invention has for its object a pole or structure to be mounted at oneend on a bus in any of the usual well known ways, and upwardly springpressed, and arranged to carry current collecting means at the other endand in the case of trackless trolley operation where the cars areinsulated from the ground by rubber tires and it is necessary to use twooverhead conductors, a positive and a negative, the collecting devicesare so mounted as to permit their separation to be varied to meetchanges in the spacing of the conductors and to meet variations inrelative vertical height of the conductors.

My invention also permits the bus to operate many feet to either side ofthe conductors under which condition the trolley pole must make aconsiderable angle with the bus and conductors and permit the currentcollectors to maintain their relation with each conductor.

In the accompanying drawings-- 7 Fig. 1 shows a top planview of myinvention with current collectors mounted thereon and insulatedtherefrom. Fig. 2 shows a side view in elevation. Fig. 3 shows a topplan view enlarged of a portion of the head member shown in Figs. 1 and2.

Fig. 4 is a section of Fig. 3 on line 4-4. Fig. 5 is a section of Fig. 3on line 5-5. In the form shown and described a portion of a pole 1 isshown, it being understood that the length may be anything desired. Tothe end of the pole is secured a head H mounted to swivel about the axisof the pole 1 to a limited degree and to carry the arms 2 which may beof metal or insulating material such as wood or bamboo. When the armsare of metal I insert between the fork members F and the arms 22 aninsulating member 3. The arms are so mounted on the head H that theirangular spacing may be'varied as re uired under operating conditions.The hea H is provided with a sleeve 4 secured to the shaft by a key Oneend of the sleeve is provided with a collar 5 having two slots 6-6therein. The opposite end of the collar is provided with a screw threadand collar 7 engaging therewith and maintains the body 8 in position onthe sleeve. The body 8 is mounted to 1'0- tate or pivot to a limiteddegree upon the sleeve 4 and the rotation is limited by projecting lugs9-9 engaging the end walls 10 of the slots 6-6.

To the body 8 are pivotally mounted a pair of clevis members 11 eachprovided with a socket 12 toreceive the arm 2. Each clevis member ismounted on the body 8 by means of the anti-friction members 13 13 andthe bolt and nut 14. The clevis-members 11 are limited as to the amountof swivel by means of the set screws 15 engaging adjacent portions ofthe body.

The pivotal joint secured by the head H permits easy adjustment of thecollectors F due to the swinging of the bust or the variable height ofthe conductors or both, and the pivotal joint secured by the clevis 11permits the transverse distance between the collectors to vary due toany variation in the spacing of the conductors or the operation of thebus to either side of the center line of the conductors.

If not desired to have the two arms 2-2 secured to one pole member 1 butto operate with each'collector and arm attachedto its own pole 1,;it isquite evident this is a simple change which can be madeby .making thehead I-I with a single arm connection. With the collector insulated fromthe arm it is necessary to connect to the collector a cable whichconducts the current to the bus.

Having shown and described my invention, I claimi 1. The combinationwith a plurality of conductors of a support comprising a main member, a.head swivelly mounted thereon to rotate about the axis of the mainmember, a plurality of arms pivotally mounted upon the head to move in acommon plane'and forming angles with said axis andmeans for theattachment of current collecting means: to each of the arms to engagethe conductors.
